If you have the acpi-support package installed, and you close the lid then a script will be run to attempt to suspend the laptop in some way. If you are using the default Etch install then the kernel will not support some of the nx6320 and I would recommend building yourself a 2.6.20.9 kernel (which is what I have been using most successfully).

Even with that kernel though, the keyboard won't work after resume from ram using the version of s2ram from the 'uswsusp' package in Etch. At present I use the following script to suspend to ram:

#!/bin/bash
#

/etc/init.d/ipw3945d stop

MODULES="ipw3945"

for M in $MODULES ; do
  rmmod $M
done

sync
sleep 1
chvt 1

# Unbind the AT keyboard interface.
if [ -f /sys/bus/platform/drivers/i8042/unbind ]; then
  echo -n "i8042" > /sys/bus/platform/drivers/i8042/unbind
fi

sleep 1

# Assuage paranoia
sync

# Force the s2ram (needed until s2ram recognises this laptop).
s2ram -f

sleep 1

# Reload the modules we got rid of earliler
for M in $MODULES ; do
  modprobe $M
done

# Rebind the AT keyboard interface.
if [ -f /sys/bus/platform/drivers/i8042/bind ]; then
  echo -n "i8042" > /sys/bus/platform/drivers/i8042/bind
fi
